Hyunwoo Kim 2a6a4e69f2 vsock/virtio: Initialization of the dangling pointer occurring in vsk->trans

commit 6ca575374dd9a507cdd16dfa0e78c2e9e20bd05f upstream.

During loopback communication, a dangling pointer can be created in
vsk->trans, potentially leading to a Use-After-Free condition.  This
issue is resolved by initializing vsk->trans to NULL.
